Remove the brake hose and wheel speed sensor
Caution:
●Check whether the brake hose is normal according to the
maintenance table.
●Before disassembl ing the brake hose, drain the brake fluid
before operation.
●Before removing the hose, remove the upper cover of the
front and rear disc brake main pump, loosen the disc brake
oil pipe bolts from the front and rear disc brake calipers to
drain the brake fluid.
●The discharged brake fluid needs to be properly disposed
of, and it is forbidden to continue to use it. It is forbidden to
dump at will to pollute the environment; or put it at will, etc.
It should be handed over to a qualified recycling unit for
proper disposal.
●The M125 /350 steps are similar to the M310, taking the
M310 as an example.
Release brake fluid
a. Refer to the previous steps to remove the oil pan first,
place the oil pan at the front and rear calipers, remove the
disc brake oil pipe bolts and copper pads first, and drain the
brake fluid into the oil pan, and then refer to the front and
rear disc brake main pumps. Add brake fluid step to remove
the upper cover of the main pump to accelerate the
discharge of brake fluid. Remove the disc brake oil pipe bolts
and copper pads at the main pumps of the front and rear disc
brakes. Only the disassembly steps of the brake hose are
explained here.
b. Press the buckle indicated by the arrow, turn the plug
push rod in the direction indicated by the arrow, and pull out
the plug. In order to prevent the remaining brake fluid from
entering the plug when the hose is removed in the next step,
the plug of the hydraulic control unit can be wrapped with an
oil-resistant film plastic bag.

RMC-HU: Rear disc brake main pump-hydraulic control unit
RC-HU: Rear disc brake caliper-hydraulic control unit
Use oil-resistant plastic bag or plastic film to put it around
the bottom of the hydraulic control unit, and fix it with tape
to prevent the residual brake fluid from dripping on the parts
when the oil pipe nut joint is loosened. M310 use a 12#
open-end wrench to loosen the oil pipe nut joints at the
hydraulic control unit counterclockwise, M350 use 14# open-
end wrench. The nut torque: 18N.m (1.8 kgf.m, 13 lbf. ft).
Wipe up the remaining brake fluid with a clean non-woven
fabric. Take care to take protective measures and prevent
dripping onto the cover or cable connector.
FMC-HU and RMC-HU
Use an 8# sleeve to remove the bolt ⑴ that fixes the seat
of the oil pipe, pull down the upper part of the FMC-HU hose,
